Abstract
Using animal models for autoimmune diseases, we have previously shown that allogeneic bone marrow transplantation (allo BMT) can be used to treat autoimmune diseases. Using cynomolgus monkeys, we have recently developed new BMT methods for the treatment of autoimmune diseases. The methods include the perfusion method (PM) for the collection of bone marrow cells (BMCs), and intra-bone marrow (IBM)-BMT for the direct injection of collected whole BMCs into the bone marrow cavity. The PM, in comparison with the conventional aspiration method, can minimize the contamination of BMCs with T cells from the peripheral blood. Therefore, without removing T cells, no graft-versus-host disease (GvHD) develops in the case of the PM. Since BMCs collected by the PM contain not only hemopoietic stem cells (HSCs) but also mesenchymal stem cells (MSCs), the injection of both cells directly into the bone marrow cavity (IBM-BMT) facilitates the engraftment of donor hemopoietic cells. In organ allografts with IBM-BMT, no graft failure occurs even if the radiation dose is reduced. In addition, IBM-BMT is applicable to regeneration therapy and various age-associated diseases such as osteoporosis, since it can efficiently recruit donor-derived normal MSCs. We have also found that IBM-BMT in conjunction with donor lymphocyte infusion can prevent GvHD, but suppress tumor growth. We believe that this strategy heralds a revolution in the field of transplantation (BMT and organ allografts) and regeneration therapy.

Abstract
The clinical use of autologous stem cell transplants for the treatment of refractory severe autoimmune diseases was preceded by convincing proof of its underlying principle in animal models. The various categories of experimental autoimmune disease in laboratory rodents are briefly described here, and the rationale that was used in the selection of suitable experimental autoimmune diseases for translational research is explained. The two models that provided the bulk of the data needed for designing the initial clinical treatment protocols were adjuvant arthritis (AA) and experimental allergic encephalomyelitis (EAE), which were both induced in Buffalo rats. In this strain, AA is manifested as a chronic, progressive, systemic polyarthritis and EAE as a chronic, remitting/relapsing form of encephalomyelitis resembling multiple sclerosis. Both diseases can be cured with autologous stem cell transplantation provided that adequate conditioning is given and that the disease has not yet progressed to the stage of 'scarring'. It is basically the inflammatory stages that respond well to this therapy. The success of treatment depends on how completely the autoantigen-specific activated T-lymphocytes and memory cells are eradicated. Because of a lack of information on the nature of the autoantigens involved in human disease and on the size of those cell populations in the animal models as well as in humans, this aspect of translation is difficult. The experiments have, however, provided important guidelines. High-dose conditioning regimens yield better results than low-dose conditioning, certain conditioning agents perform better than others, and care should be taken not to reintroduce too many T-cells with the autologous graft. The clinical results obtained so far indicate a high predictive power of these two animal models, which are therefore recommended strongly for additional preclinical studies.

Abstract
Vascularized allogeneic skeletal tissue transplantation without the need for host immunosuppression would increase reconstructive options for treating congenital and acquired defects. Because the immune system of a fetus or neonate is immature, it may be possible to induce tolerance to allogeneic skeletal tissues by alloantigen injection during this permissive period. Within 12 hours after birth, 17 neonatal Lewis rats were injected through the superficial temporal vein with 3.5 to 5 million Brown Norway bone marrow cells in 0.1 ml normal saline. Ten weeks after the injection, peripheral blood from the Lewis rats was analyzed for the presence of Brown Norway cells to determine hemopoietic chimerism. The Lewis rats then received a heterotopic, vascularized limb tissue transplant (consisting of the knee, the distal femur, the proximal tibia, and the surrounding muscle on a femoral vascular pedicle) from Brown Norway rat donors to determine their tolerance to the allogeneic tissue. A positive control group (n = 6) consisted of syngeneic transplants from Lewis rats into naive Lewis rats to demonstrate survival of transplants. A negative control group (n = 6) consisted of Brown Norway transplants into naive Lewis rats not receiving bone marrow or other immunosuppressive treatment. The animals were assessed for transplant viability 30 days after transplantation using histologic and bone fluorochrome analysis. All the syngeneic controls (Lewis to Lewis) remained viable throughout the experiment, whereas all the Brown Norway to Lewis controls had rejected. Ten of the 17 allografts transplanted into bone marrow recipients were viable at 30 days, with profuse bleeding from the ends of the bone graft and the surrounding graft muscle. The percent of chimerism correlated with survival, with 3.31 percent (SD = 1.9) of peripheral blood, Brown Norway chimerism present in the prolonged survival groups and 0.75 percent (SD = 0.5) of Brown Norway chimerism in the rejected graft group. This study demonstrated prolonged survival of allogeneic skeletal tissue without immunosuppression after early neonatal injection of allogeneic bone marrow in a rat model.

Abstract
Diabetogenic Coxsackievirus B4 infection produces a diabetes syndrome in susceptible mice resembling insulin-dependent diabetes mellitus. We reported a two- to threefold increased expression of a 64,000-Mr (64 K) islet autoantigen in the infected mice preceding the development of hyperglycemia, suggesting a possible role of the virus in autoimmunity. To assess if the virus could be a trigger of autoimmunity, 64 K autoantibody development was correlated with hyperglycemia and virus replication in islets during early and late infection. Additionally, the effects of blood removal from these mice on the incidence of hyperglycemia and antibody production were evaluated. Noninfected control mice were essentially 64 K antibody negative, the infected consistently positive. Approximately 30% of the animals developed antibodies by 72 h postinfection (p.i.) and 90% by 4-6 wk p.i. Virus-induced hyperglycemia appeared bimodal: hyperglycemia in 50% of the mice by 1 wk p.i., which decreased to 30% by 3 wk and then increased to 80-100% by 6 wk p.i. Infectious virus was abundant in the islets at 72 h but undetectable later. Hyperglycemia seen at 6 wk decreased dramatically (67-73%) if the mice were bled once between 72 h and 2 wk p.i. Only 50-60% of the mice bled once were 64 K positive compared to 90% positive nonbled mice. Coxsackievirus may initiate or enhance the autoimmune response.

Abstract
During the last 25 years the concept of a chronic autoimmune process leading to the development of insulin dependent diabetes (IDD) has emerged. The presence of two animal models for IDD, the BB rat and the NOD mouse, has improved our ability to understand the process leading to beta cell destruction. The hallmark of an autoimmune disease is the characteristic pathologic lesion of mononuclear infiltration of the pancreatic islets. Further histologic studies of the diabetic pancreas have identified the type of cells infiltrating the islets and led to the concept of pancreatic beta cells capable of presenting antigen. The initial description of linkage disequilibrium of HLA DR3 and DR4 alleles with IDD has now progressed to the molecular level with the identification of residue 57 of the HLA DQ beta chain as crucial to the genetic predisposition to IDD. Autoantibodies to cytoplasmic antigens (ICA), surface antigens, or a membrane protein of 64 kDa identified by immunoprecipitation, autoantibodies to secreted products such as insulin and proinsulin, and autoantibodies that are cytotoxic to cultured beta cells are islet specific autoantibodies that have been described. Some are probably only markers of immunologic activity; others might participate in the destruction itself. The use of ICA as a screening tool has been successful in identifying individuals prior to the onset of IDD. Widespread cellular immunological defects have been identified both in animal models and in man. In the BB rat, a seeming paradox of severe immunodeficiency occurs in an animal with autoaggressive destruction of beta cells. More subtle defects in immunoregulation have been described in the NOD mouse and in human IDD. The response of IDD in both animal models and in man to immunomodulation and to immunosuppression offers further evidence of an immunologically mediated disease. However, some therapies in the animal models, not typically considered immunologic, such as protein restriction and insulin therapy, have prevented IDD. The possibility of intervening prior to the onset of clinical disease at the level either of the initial process of recognition of the pancreatic beta cell as a target organ or of the effector mechanism is approaching a reality in human IDD.

Abstract
It is now well known that insulin-dependent diabetes is a chronic progressive autoimmune disease. The prolonged prediabetic phase of progressive beta-cell dysfunction is associated with immunological abnormalities. A prediabetic period is suggested by the appearance of islet cell antibodies, anti-insulin antibodies, and anti-insulin receptor antibodies. The existence of activated T lymphocytes and abnormal T cell subsets are also other markers. There is still no concensus about the use of the immunosuppression superimposed upon conventional insulin therapy in early diagnosed IDDM and the follow-up of the relatives of IDDM patients who share the genetic predisposition and serological markers for the risk of future onset of IDDM. Treatment in the prodromal period cannot be justified because a link between the disease and early markers such as ICA has not been established with certainty (Diabetes Research Program NIH, 1983). Many immunopharmacological manipulations were reported to be effective in animal models. However, most of them are not readily applied to human subjects. Moreover, IDDM patients are now believed to be heterogeneous, with a complex genetic background. HLA-DR, and more recently DQ, are closely related to the genetic predisposition to IDDM but those genes are not themselves diabetogenic. The contribution of autoimmunity does not appear to be uniform, and in some cases, the contribution of virus is considered more important. There is a lack of a marker for the future onset of IDDM. ICA and ICSA were found after mumps infection, but the existence of those autoantibodies and even the co-existence of HLA-DR3 do not always indicate the future trend to insulin dependency. More precise markers will be disclosed through the biochemical analysis of the target antigens on pancreatic beta-cell for islet antibodies and effector T cells. Much safer and more effective immunopharmacological treatment will be developed through animal experimentation using rat and mouse models. The recent development and interest in this field will further facilitate the attainment of the goal for the complete prevention of IDDM.

Abstract
To investigate the role of RT6+ T cells in the pathogenesis of diabetes in BB/W rats, we treated animals from the diabetes-resistant (DR) subline with anti-RT6.1 lymphocytotoxic mAb. This depleted greater than 95% of peripheral RT6+ T cells but did not substantially reduce levels of circulating T cells or the in vitro response of spleen cells to mitogen. Treatment of 30-d-old DR BB/W rats in this way: induced insulitis and diabetes, rendered nondiabetic RT6-depleted DR rats susceptible to the adoptive transfer of diabetes by spleen cells from acutely diabetic BB/W rats, and yielded DR spleen cell populations capable of the adoptive transfer of diabetes to diabetes-prone (DP) or DR recipients. Treatment of DR rats beginning at 60 d of age failed to produce these effects. These results suggest that both susceptibility and resistance to diabetes in the BB/W rat are in part regulated by the RT6+ T cell subset and provide evidence for the importance of regulatory T lymphocytes in the pathogenesis of autoimmunity and diabetes in BB/W rats.

Abstract
Autoimmune diabetes can be transferred to young, diabetes prone BB/W rats by injecting them intravenously with concanavalin A (Con A)-treated spleen cells from acute diabetic BB/W donors. This study describes the transfer of diabetes to the normal Wistar-Furth strain of rats using a similar procedure. For the successful transfer of diabetes it was necessary to immunosuppress recipient animals with a single intraperitoneal injection of cyclophosphamide 24-48 h before administering Con A-stimulated spleen cells from acute diabetic BB/W rats. Of 68 Wistar-Furth rats in immunosuppressed with a dose of 100-150 mg cyclophosphamide/kg body wt, 10 (15%) became diabetic. None of the control rats receiving either Con A-stimulated Wistar-Furth spleen cells (n = 28), freshly isolated BB/W spleen cells (n = 14), or fresh RPMI medium (n = 11) became diabetic. These data indicate that diabetes can be transferred from BB/W to Wistar-Furth rats. In addition, they support the hypothesis that cell-mediated immune processes are involved in the development of insulin-dependent diabetes and rule out any absolute requirement for BB-derived genes in the target pancreatic beta cells.
